II - RADIO ANTI-THEFT FUNCTION
The radios do not have an LED which flashes when the vehicle is stationary.
The anti-theft protection device is provided in the form of an identification code. It
consists of the last 8 characters of the VIN, memorised by the BSI and the radio.
Note: Radios are supplied by the Replacement Parts Division with a memorised
VIN code.
When operating, the radio's VIN code is compared with that of the BSI. If they do
not correspond, the radio switches to scrambled mode.
Note: The VIN code cannot be reprogrammed in the BSI.
Consequently, the radio VIN code must be changed using the diagnostics tool if a
new radio is fitted.

III - CONTROLLING THE BRIGHTNESS

The RD2 alters its brightness as a function of the value given by the BSI.
The brightness of the RB2 cannot be adjusted.

IV - VOLUME AUTOMATICALLY LINKED TO VEHICLE SPEED

RB2 and RD2 radios automatically correct the volume as a function of speed if the
following 2 conditions are fulfilled:
• the configuration via the "Volume automatically linked to speed" diagnostic is
ON,
• the user has activated, via the radio menu, the automatic volume correction
(VOLUME_AUTO = ON).
This function does not affect the volume displayed on the screen and is controlled
within the radio.
Note: The values of the volume are transmitted to the multifunction screen during
adjustment.
It is still possible to adjust the volume manually using the "ON/VOL" button or the
steering wheel remote control at any time and is independent to automatic
correction.
